Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
572 lbs / 259 Kg = 14.1 x 4.3 " / 110 mm shells or 0.3 torpedoes
Stability (Unstable if below 1.00): 1.22
Metacentric height 1.6 ft / 0.5 m
Roll period: 12.1 seconds
Steadiness - As gun platform (Average = 50 %): 70 %
- Recoil effect (Restricted arc if above 1.00): 0.40
Seaboat quality (Average = 1.00): 1.07

Hull form characteristics:
Hull has rise forward of midbreak
and transom stern
Block coefficient: 0.400
Length to Beam Ratio: 10.00 : 1
'Natural speed' for length: 21.95 kts
